Hi Gina,
I hope you're doing well! I'd recommend joining the local tennis club. It's a great mix of fun and fitness, and you can develop teamwork and focus. Tennis also enhances agility and mental sharpness. Plus, the social aspect is fantastic! You'll meet new people and build lasting connections. Give it a shot, and I'm sure you'll love the experience.
Best,
